Abstract
Residual aldehyde levels in bioprosthetic tissue are reduced by contacting the tissue with a rinsing solution such that aldehyde which has diffused out of the tissue into the rinsing solution comes into contact with, and reacts with, an amine, thus causing further diffusion of aldehyde out of said tissue. The amine may be dissolved in said rinsing solution or may be immobilized on a solid support to which the rinsing solution is periodically or continuously exposed.
